DLA-2392-1 jruby -- LTS security update

Date Reported:

01 Oct 2020

Affected Packages:

jruby

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2020-25613.

More information:

A potential HTTP request smuggling vulnerability in WEBrick was reported.

WEBrick (bundled along with jruby) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to “smuggle” a request.

For Debian 9 stretch, this problem has been fixed in version 1.7.26-1+deb9u3.

We recommend that you upgrade your jruby packages.
